You're doing well Catherine

I used to call that cluster feeding/nipple tugging "crazy time". Bub seemed to be crazy for it for a couple of hours. If you can manage alright without offering the formula then that is terrific. I understand how much it is a self doubt thing. I've been there myself many times. Even third time round the self doubt is there. The thing that got me through is the output and knowing that it will get easier one this little stage passes

280g is a great weight gain! Well done!
